Servers
Adding and Modifying Servers
Servers can be added and modified using either the GUI or the CLI
Parameters
The table below shows the parameters, values, and flags used in the configuration Servers.
GUI Parameter (CLI Parameter) Description
IP
(
ip )
The dotted decimal IP address of the server. This is the address Equalizer
uses to communicate with the server.
Port
(
port )
Enter the numeric port number on the Equalizer to be used for traffic
between Equalizer and the server. The default is port 80. (Note that in
Layer
7 HTTPS clusters, the server port should be set to something other than 443
since Equalizer communicates with servers in an HTTPS cluster via HTTP.)
For L4 UDP and L4 TCP protocol clusters, a cluster port range can be
defined. These are the ports on the Equalizer to be used to send traffic to
the server pool in the cluster. Port ranges allow Equalizer users to create a
single cluster to control the traffic for multiple, contiguous ports. The
Port
defined for a server in the cluster for which a port range is defined indicates
the port on the server that starts the range of ports to be opened.
Maximum Reused Connections
(
max_reuse_conn )
By default, the Maximum Reused Connections server option is set to 0,
which means that Equalizer will route traffic to the server whenever the
server is selected by the current load balancing settings. If
Maximum
Reused Connections is set to a value greater than 0, then Equalizer limits
the total number of simultaneously open connections to the server to that
value. This restriction applies regardless of the persistence options set on
the cluster.
When a server reaches the specified limit, requests will not be routed to that
server until the number of active connections falls below the limit.Typical
reasons to set a maximum number of connections include:
•Implementing a connection limit that is required due to software lim-
itations, such as an application that can service a limited number of con-
current requests.
•Implementing license restrictions that are not enforced by software;
such as limiting the number of active connections to an application that
is licensed for a limited number of concurrent connections.
•Setting a threshold that will limit resource utilization on the server.
Reused Connection Timeout
(
reuse_conn_to )
The number of seconds after which a connection record for an idle server
connection in the reusable connection pool is removed, and the connection
closed. The default value is
0
seconds, which means that records in the
reusable connections pool never expire.
